SREVIEW-CUT(1p)

NAME
sreview-cut - cut a talk out of the raw recording data

SYNOPSIS
sreview-cut TALKID

DESCRIPTION
"sreview-cut" performs the following actions:

•   Look up the talk with id TALKID in the database

•   From the raw files, extract the amount of video that, according to the schedule, is part of the talk of which the event was given as the main video (with adjustments as specified by the reviewer, if any, applied).

•   Extract the 20 minutes just before and the 20 minutes just after the main video into the pre and post videos.

•   Apply A/V sync correction values if any exist.

•   Perform audio normalization, if enabled in the configuration

•   Extract sample videos from all three channels into preview audio streams, if enabled in the configuration

•   Move the talk to the next state.

sreview-cut will only re-encode those parts of the original video that have to be re-encoded in order to make sure that the video that is finally produced starts with a key frame, and will re-encode the original audio of the main video at most once, after audio normalization if that was enabled in the configuration.

Any re-transcodes should be performed by "sreview-transcode" (for production) and/or "sreview-previews" (for review previews)

CONFIGURATION
"sreview-cut" considers the following configuration values:

workdir
    The location where any temporary files are stored. Defaults to "/tmp", but can be overridden if necessary. These temporary files are removed when "sreview-cut" finishes.

dbistring
    The DBI string used to connect to the database.

audio_multiplex_mode
    The way in which the primary and backup audio channels are encoded in the video. Can be one of:

    stereo
        The primary audio is in the left channel, and the backup audio is in the right channel.

    stream
        The primary audio is in the first audio stream (a mono stream), and the backup audio is in the second audio stream (also a mono stream).

    none
        There is only one audio stream, and if it is a stereo channel then the right channel is not the backup audio.

inputglob
    The location of the (raw) input files. These files should have been put into the database by way of "sreview-detect"

pubdir
    The location of the intermediate files that are published to reviewers.

accessmethods
    The SReview::Files implementation used to access the input files and/or the intermediate files.
